Daniil Medvedev will set the pace for four fellow Top 10 competitors when the European Open begins on clay next month in Hamburg.
The historic north German outing was given a reprieve when the ATP rewrote the rump season calendar prior the current resumption of Tour play after more than five months of COVID-19 lockdown.
Fifth-ranked Medvedev will be joined September 19-27 at the refurbished lakeside Rothenbaum club by ATP No. 6 Stefanos Tsitsipas, eighth-ranked Italian Matteo Berrettini, No. 9 Frenchman Gael Monfils and No. 10 David Goffin.
Medvedev owns seven ATP trophies and played the US Open final a year ago against Rafael Nadal.
Canadians Denis Shapovalov and Felix Auger-Aliassime are also due to use Hamburg to prepare for the September 27 start of the rescheduled French Open which begins on the day of the Hamburg final.
Georgian Nikoloz Basilashvili won Hamburg last July.
“Our entry list will delight many tennis fans in Hamburg. There are many stars of the new generation that we have not seen here yet,” TD Sandra Reichel said.
“The list might change a bit until the tournament kicks off, as the players’ final participation depends on their previous performances at the events in New York and Rome. Nonetheless, we can expect an excellent line-up.”
Attendance will be necessarily limited by the current virus pandemic, with only a fraction of the stadium’s 10,000 capacity to be used for fans.
